Time exposures: set the shutter-speed setting
ring (16) to B. Upon depressing the release
button (17) or the release mechanism of the
lens, the shutter will remain open for as long
as the pressure is maintained. For longer time
exposures, the shutter can be locked open as
with a “T” setting: set the shutter-speed setting
ring (16) to B, open the shutter by pressing
the release button (17) or the release mech-
anism of the lens and whilst maintaining the
pressure set the shutter release lock (13) to the
upright position. The shutter will then remain
open without any need to touch the cam- era,
until the shutter release lock (13) is moved
once again to the fight; in this way cam- era
shake can be avoided completely. Lenses with
fully-automatic diaphragms should be adjusted
for manual stopping-down, since otherwise the
diaphragm will open prematurely. When using
the Domiplan f 2.8 / 50 mm lens for long time
exposures, you should employ either the B
setting and if necessary a cable release with a
locking device, or the “T setting” with a locking
knob for the release rocker. For further details
see the section on lenses, pages 9 . . .14. The B
and T settings are particularly useful for night
and indoor pictures.
A cable release is recommended for use when
taking time exposures, (particularly with the B
setting); the release may be screwed into the
shutter release button (17) or into the release
mechanism of the lens.
For all forms of time exposure the camera
should be attached to a tripod or placed on a
firm support (table, wall etc).
The shutter speeds may be selected both be-
fore and after tensioning the shutter.
Any of the standard types of delayed-action re-
lease available f om photographic dealers may
be used with the EXA II a; these are either fitted
to the cable release, or else screwed directly
into the release button (17) or into the release
mechanism of the lens.
